CONTAINER FOR COLLAPSIBLE TUBES.`

Application filed August 9, 1926.

adopted the collapsible metallic tube as a i container for a widevariety of toilet articles,

foods, pigments, and the like. Possibly the widest use thereofexistswith respect to dentifrices, toilet and shaving creams which insuresundeniable convenience and advantage, coupled with certaindisadvantages, such as loss of the contents through excessive or poorlycontrolled expulsion thereof from the tube, or a failure to expel theentire contents. Moreover, a partly used collapsible tube commonlybecomes untidy and it is inconvenient to care for it on a dressing tableor, the like.

Accordingly, it has been my further object to provide a suitableoperating container' for collapsible tubes, which will be handy :foruse, neat in appearance, and insure the gradual expression of thecontents of an inserted tube, without waste or loss. This, almost ofnecessity, must be actuated with one hand, while it is obvious that thearticle must be simple, cheap to manufacture, and attractive inappearance. These features will be found adequately combined in theembodiment of my invention illustrated in the accompanying drawings,wherein:

Figure l, isa view of said device or container in front elevation.

Fig. 2, is a side elevation thereof.

Fig. 3, is a vertical section showing the inserted tube.

Fig. 4., is a similar sectional view, showing, in addition, the partlycollapsed tube, and indicating the mode by which its contents may beevenly and completely expressed.

Fig. 5, is an enlarged fragmentary view, partially broken away and insection, showing the flexible expressing member of my improvedcontainer, and

Fig. 6 is a view thereof in side elevation.

Throughout the several figures of the drawings I have employed the samecharacter of reference to indicate similar parts.

The container, as shown, comprises a metallic body portion a, open atthe front a', and provided with a removable cover b. When the cover isremoved, the collapsible Serial No. 128,276.

tube c may readily be inserted within the container so that its threadedneck c protrudes through a circular opening b provided in said cover.'When the cover is in place, the screw cap c may be adjusted upon thetop of thc tube to protect its contents until wanted for use.

Although the container securely protects an inserted collapsible tube,and the contents might be manually expressed by inserting the `thumb toapply pressure through the Yfront opening, I prefrerably provide meansfor grat ually and evenly applying such pres- The particular means shownconsists of a readily flexed member cl, made up of flattened metallictubular sections d', terminally united b the U-shaped links el, so thatsaid memliers may readily move with respect to each other and insureiiexibility `for the expressing member, as a whole.

Said expressing member is supported rearwardly of the opening in thecasing,r by a transverse pin e, so that it hangs as a flexible closurerearwardly of the opening a', with its edges laterally engaged by theside pieces a. lhus, member d atl'ords sufficient rigidity, vertically,to transmit applied pressure evenly and effectively to the front of thetube, beginning from the bottom up, so that it may be gradually butcompletely collapsed, just as the contents are required for use.

This operation may be accomplished by the thumb pressure of one hand, sothat the tube c finally is completely collapsed as a flat metallicribbon, excepting only a negligible portion at the upper extremity ofsaid` tube. The flexibly mounted tubular links or sections tl, it willbe Seen upon referring to the lower portion of Fig. Ll, evenly transmitthe applied pressure to the body of the collapsible tube c, so that allof the contents graduall is displaced withoufloss or waste and unc erthe complete control ot the user in a manner not obtainable with thefingers alone. It is seen that the body of the tube becomes flatlycompressed between the parallel faces of member cl and the rcar wall ofthe container a, as they are approxi Claims; hence donot Wishjto beunderstood :is limiting, tle seine to the details of c`nstruction hereinset forth :is embodying my instant in'ipi'ovenients.
